HEATING-STOVE.

Specification of Letters Patent.

iatented Dec/J7, 1909.-

Application filed March 10, 1909. Serial No. 482,519.

To all who'm it may concern:

Be it known that I, HERMAN F, AREN- BERG, a citizen of the United States, residing at Petahnna, in the county of Sonoma and State of California, have invented new and useful Improvements in Heating-Qtoves, of which the following is a specification.

My invention relates to a heating stove, preferably of that class in which oil with the proper burner may be employed as a heating medium; and the stove may be employed in connection with incubators or brooders for young fowls.

It consists in the combination of parts, and in details of construction which will be more fully explained by reference to tho accompanying drawings, in which Figure 1 is an cle ation and partial section of the apparatus. Fig. 2 is a cross section on line ar zc of Fig. l.

The device consists of an exterior conical casing A which may be made of metal or other suitable material, and the bottom of this casing is supported in or upon a suitable base which may be tilled with concrete or other material if desired. Upon this base, and within the casing A, is fixed a suitable oil burner. Such a burner is partially shown at 3.

The front. or any desired portion of the base i may have an opening 4 made for the admission of air which enters below the burner, and passes up through openings t around and through the burner as it furnishes the lirst oxygen for the combustion of the fuel. which may be a suitable grade of hydrocarbon oil. The diliiculty in employing such fuels is the production of a great. quantity of unconsunied carbon in the form of soot which soon reduces the heating value of the apparatus, and makes it necessary to clean it frequently. in order to overcome this objection, l have shown a series of air inlet openings, as at- 5,1nade through the side of the conical shell A at intervals between the bottom and the top. In the present case I have shown the first series as contiguous to the burner; these openings extending horizontally around a casing at desired intervals.

Exterior to the casing is a flange,-the interior portion of which is in the form of a ring (3 having the same taper with the outside of the cone, and an interior diameter such that when it rests upon the cone, it substantially tits against the side, and the taper the lower edge of the ring might be of the two prevents the ring from slipping down any farther.

It will be manifest that if found desirable,

supported upon legs orprojections of any character which would insure its remaining in the proper position. Through this ring are made holes or openings corresponding with the holes 5, and in line therewith.

The ring is freely turnable around the cone, and when turned a certain distancethe holes in the ring will be out of line with those in the casing, and the draft through these openings will thus be entirely closed. 3y turning the ring the openings may be made to register to a greateruor less degree, and thus supply any desired quantity of air at this level. Above the burner are other similar rings, as at 6*, as many being employed as may be found desirable betweer the bottom and top of the conical casing. The upper edge of each of these rings connects with an upwardly flaring hood 7 having a greater divergence than the rings themselves, and this forms a channel open at the bottom and gradually converging to the apex where it meets the top of the ring (3. The air that passes through the draft openings thus enters beneath this projecting flange or hood and enters the draft openings. The inclination or bevel of these hoods is such that it will prevent young fowls from perclnng upon the device, or get-' ting too closely against it where it is used in a brooder.

From the top of the cone a smoke-stack or pipe 8 extends upwardly, and aroun 1 this is hired an umbrella shaped cone 9 of considerable diameter, extending preferably beyond the base 2.

The device may beused in any relation where a moderate degree of heat is'required, but is especially designed for use in brooders for young fowls where it is desirable to maintain an even temperature.

The operation will be as follows: The hydrocarbon having been ignited at the burner, a first supply of air enters through the opening 4, passing up throu h and around the burner in any manner esigned. for the burner. Around the outside through the first series of openings 5, airmay be admitted as found necessary or desirable, to mingle with the products of combustion as they leave the burner. As these products of combustion rise, they will be more per- 'nustion thus kept up and prevented from 'l'eetly consun'icd than when first delivered from the burner, and when they reach the second series of openings 5, another body of air admitted, the size of the 'openings being-graded to suit requirements. The comdeteriorating, and when' t'he products of combustion have reached the next of the air supply o iienings 5, another body of air is admitted. Thus air may be admitted as often as is "iound desirable, and the result will he to continue the comb etion within the apparatus, and to hirgeiy prevent the deposit of nnconsumed carbon. The heat de\elopcd arising from the outside of the cone will be arrested by the deflector 9 and thrown downward into the bottom of the chamber within which the device is placed, and it such a chamber be employed as a breeder lor young fowls there will be a steady heat thrown downwardfrom above into the lower part of the chamber.

It will be understood that; the temperature may be readily ascertained by means of a iiunmometer, and by regulating the air and oil simply an even and. steady lBIHPBLiLlIHTB may be maintained. i

The shape of the device and the projecting heads or flanges 7 will prevent the young towls from coming in actual. contact with the stove, or perching upon any ledges or projections thereon to their own injury. The flanges 7 extend down below the draft openings 5, thereby stopping any light rays that might disturb the young chicks.

Having thus described my invention, what 1 claim and desire to secure by Letters Pat,- ent is- It. heating device consisting of an exterior conical easing,-and a supporting base, an oil burner located in the lower part of the casing, means for supplying air directly to the burner, a series of supplemental air inlets surrounding the casing at ditierent elevations, and means for controlling the admission of air thereto, said last named means comprising perforated sleeves rotatively mounted on the casing adapted to have their pert'o 'ations moved into or out of register with the air inlets, said sleeves having portions overhanging the inlets.

it; in an apparatus of the character described, an upwardly convergent conical casi ing,-and a supporting base having an air inlet, ahydrocarbon burner located above the air inlet, a series of air inlet openings through the sides of the casing disposed in series between the bottom and the top,

sleeves fitting and turnable'upon the sides of the casing, said sleeves having hood portions overhanging the alr inlets, and sold sleeves having openings adapted to register- 3. In an apparatus of the character described, a conical upwardly convergent casing, and a base upon which it is supported, a hydrocarbon burner located in the lower partof the casing, means for supplying air directly to said burner through the base, a-

series of openings made inlhorizontal planes at different elevations between the bottom and top of the casing, sleeves fitting the easing at these points having openings there through, said sleeves being turnable to cause the openings to register with, or out other limit, the size of the openings in the casing, and downwardly divergent flanges connecting with the up er edges of the sleeves, and projecting-over the air inlet openings.

4. In an apparatus of the character described, a conical upwardly converging casing, a supporting base, a burner centrally located near the lower part of the casing, means lior supplying lair directly to. the burner, a series of openings through the casing in horizontal planes between the bottom and the top, corresponding sleeves fitting the casing and having openings adapted to register with those of the casing, and control a supplemental air supply, said sleeves having downwardly and outwardly diverging flanges forming guides for directing the air through the openings, and a conical deflector fixed around the top of the cone, and extending outwardly. therefrom.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
